WINDOW-SASH ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 689,249, dated December17, 1961.

Application filed July 13, 1901.

To all whom it may concern..-

\ Be it known that I, IRA E. TRANTER, of Franklin, county of Johnson,and State of Indiana, have invented a certain new and useful Window-SashAttachment; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, in which like figures refer to like parts.

The object of this invention is to provide an improved means forenabling a windowsash to be rotated without removal from the frame forwashing or cleaning the same or for any purpose, and to hold said sashin the position in which it might be placed.

Another object is to provide an improved arrangement of spring-pressedweather-strip for the window-sash.

These and the other features of my invention will appear from theaccompanying drawin gs and the following description and claims.

In the drawings, Figure 1 is an elevation of the upper portion of awindow, the lower part being broken away. Fig. 2 is a central verticalsection with the upper sash partially rotated. Fig. 3 is a verticalcentral section crosswise through one side of the windowsash and theadjacent parts near the middle of the sash, the upper and lower partsbeing broken away. Fig. 4 is a horizontal crosssection of what is shownon the line 4 4 of. Fig. 1, parts being broken away. Fig. 5 is a plan ofthe adjacent faces of the two plates that form the ball-bearin gs bywhich the window-sash is mounted.

There are various ways of carrying out this invention and constructingthe device. One method is to saw ofi from each side of a window-sash 10a guide-bar 11. This is desirable where old window-sashes will beprovided with my invention; but where the window is made in view ofmyinvention the guide-bars 11 may be made independent of the windowsash.The guide-bars 11 are in one sense only the side edges of the sash andslide up and down in the window-frame which is made in the ordinary way.My invention does not change any part of the window-frame, but onlychanges the construction of the sides of the window-sash. Thewindow-frame, as

Serial No. 68il88. (No model.)

as shown in Fig. 4, to make the recess 14,

that extends longitudinally from the top to the bottom of theguide-bars. In it I place the weather-strip 15, that likewise extendsfrom top to bottom, and between the weatherstrip 15 and the guide-bar 14within the recess I place the springs-16, secured to either member andpressing the two apart-that is, pressing the Weather-strip 15 outwardfrom the recess 14 and away from the guide-bar 11.

The springs 16 are secured between the guide- 6 bar and weather-strip bythe screws 17, with the head movable in a countersunk hole in theweather-stri p to hold. the spring in place and prevent independentvertical movement of the guide-bar and weather-strip, yet permit lateralmovement of the weather-strip.

The window-sash is pivotally'mounted 'tof and between the weather-stripsl5 and is in no wise secured to the guide-bars 11. The

means for making this pivotal connection is shown in Figs. 3 and 5. In asuitable recess made in the side of the sash I secure the plate 20 byscrews through the arms 21. This plate has ball-seats 23, connected byball-races 22;

but the ball-races 22 are not as deep as the ball-seats 23. Thecompanion plate 24 is provided with a series of ball-seats 23, butWithout any intervening ball-races 22. The flat-headed screw 25 extendsloosely through the'hole 28 in the plate 20 and is screwed into theplate 24, and plate 24 is secured to the weather-strip by the screws 26.The screw 25 is long enough to permit the partial separation of the twoplates 20 and 24, and

the spiral spring 27, surrounding the screw 25, tendsto press the plate20 against the plate 24. Balls 29 are placed in the ball-seats 23, whichcorrespond with each other in the two plates, and the balls 29 being ofthe proper dimensions the two plates 20 and 24 5 will engage each otherwhile the balls are in place and while the ball-seats correspond witheach other, as shown in Fig. 3. When, however, the window-sash is turnedinto the position shown in Fig. 2, the plate 20 will be too turned also,and in moving will ride over the balls 29 in the other plate until theball-seats 23 in the two plates again correspond, when by action of thespring 27 the two plates will be brought tightly against each other andthe balls will hold the window-sash in the position to which it ismoved. If the window-sash be pushed farther, the same change will againoccur and the sash will be held in its changed position. The advantageof this ball-bearing arrangement is that the altered position of thewindow is more easily attained, because balls are used, and less wear ofthe parts forming the pivot or holding arrangement will take place thanif no balls were used, but merely rigid jaws or corrugations. The outeredge of the weatherstrip is rounded, as shown in Fig. 4, to permit therotation of the window-sash past it, and such weather-strip fits in acorresponding vertical groove or seat in the side of the window -sash,as appears in Fig. 4. The springs 16 also act against the weather-stripsand press the plates 20 and 24 together, these springs cooperating withthe spring 27.

Where the window-sash is originally made in view of my invention, thesash, weatherstrip, and guide-bars may be made independently, and thenthey are finally assembled, as above set forth.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination with a window-sash, of a guide-bar longitudinallychanneled adjacent the window sash, a spring pressed weather-strip insaid channel between the window-sash and guide bar and a pivotalconnection between the window-sash and weatherstrip.

2. The combination with a window-sash, of I guide-bars longitudinallychanneled adjacent the window-sash, weather-strips in said chari nels,springs in said channels for pressing the weather-strips against thesash and away from the guide-bars and a pivotal connection between thewindow-sash and weather-strip.-

3. The combination of awindow-sash with its side bars groovedlongitudinally, guidebars longitudinally cha'nneled,weather-strips inthe channels of said guide-bars and fitting in the grooves in the sash,springs in said channels that press the weather-strips against the sash,and means for pivoting the sash to the weather-strips.

' 4. The combination with a window-sash, of means for pivotally mountingit consisting of a pair of plates with a series of correspondingball-seats in each plate, and ball-races connecting the'ball-seats inone plate, balls, and means for yieldingly holding the plates againsteach other.

5. The combination with a window-sash, of guide-bars on each sidethereof longitudi nally channeled, weather-strips mounted in saidchannel between the guide-bars and sash, springs for pressing theweather-strips toward the sash, a plate secured to the weatherstrips,rotating bodies mounted in said plate, another plate mounted on the sashwith a bearing-surface for the-rotating bodies that is formed ofalternating depressions and elevations,and springs that tend to pressthe plates on the sash against the plates on the weather= strips.

In witness whereof I have hereunto affixed my signature in the presenceof the witnesses herein named.-
